The Knight First Amendment Institute, a nonprofit advocacy group based at Columbia University, threatened to take legal action against President Trump if he does not unblock critics on Twitter.

The demand, made in a letter to President Trump, was sent on behalf of Holly O’Reilly and Joseph M. Papp, two Twitter users who were blocked by the president’s account after criticizing him on the social media network.

I find this interesting because I did not consider that possibility. However, if you think about it, Mr. Trump is an agent of the government is punishing people from saying things he does not like in response to his statements. It will be interesting to see where this goes.
